Obviously I'm not an LSE grad student because none of them caused more than a smile. Also, why were some jokes Americanized (dollar/quarters in the barbershop joke) but others left English (World Cup as opposed to Super Bowl in the funeral joke)?

Fwiw, here are my two favorite jokes:

Patient: "Doctor! Doctor! I only have sixty seconds to live!"

Doctor: "Can't you see I'm busy? Wait a minute."

And--

Did you hear about the baker who got electrocuted? He stepped on a fruit pie and a currant run up his leg.
